--- title: "Quick LaTex: Footnotes with no Counter" date: 2022-09-23T15:34:28-04:00 draft: false tags: ["LaTex"] math: false --- Let's say there's a scenario where you want to have a footnote, but you don't want a counter associated with it. In order to stay consistent with the document style, the solution should use `\footnote` within its implementation. The solution: Define `\blfootnote{text}` in the preamble. ```latex \newcommand\blfootnote[1]{ \begingroup \renewcommand\thefootnote{}\footnote{#1} \addtocounter{footnote}{-1} \endgroup } ``` This makes use of the footnote command while also re-adjusting the footnote counts so that our variant doesn't increase it. We can then use this command within the document. Here's a beamer example: ```latex \begin{frame}{Some Topic} This is where I explain some topic. \blfootnote{Numberless Footnote} \end{frame} ``` Complete Minimal Example: ```latex \documentclass[aspectratio=169]{beamer} \usepackage[utf8]{inputenc} \usetheme{Copenhagen} \newcommand\blfootnote[1]{ \begingroup \renewcommand\thefootnote{}\footnote{#1} \addtocounter{footnote}{-1} \endgroup } \begin{document} \begin{frame}{Some Topic} This is where I explain some topic. \blfootnote{Numberless Footnote} \end{frame} \end{document} ```
